To scriptorians, PGP means “Pearl of Great Price” but to cryptographers, it means “Pretty Good Privacy” and refers to the safe-keeping of personal information. PGP is a type of encryption the Church uses to communicate securely with other organizations, such as banks and businesses. Each day we depend on encryption to act as a computerized safe-and-key system for managing access to our data.

Phil Zimmermann, the creator of PGP, developed and released the first PGP software in 1991. He published his source code and freely gave it away for anyone to use. The software is simple to use and is designed to encrypt files and e-mail transferred over the Internet. PGP is now the most popular e-mail encryption software in the world.

How does PGP work?

PGP requires entities or individuals to create their own individual pair of encryption keys. The key pair contains a private key that is never shared with anyone and a public key that is shared with everyone. Anyone can use a public key and encrypt a file or message with it. However, only the entity or person with the corresponding private key will be able to decrypt it. This is known as a one-way function. The technical implementation of a one-way function is brilliant but simple.
